Geez, that's even more than CANADA! (no offense)
As for your first gun, be sure to try out everything, but here are some quickie tips I live by (do not feel obliged to take them seriously):
1. PLAY WITH THE TRIGGER. I can't stress this enough... good trigger pull is absolutely essential for accuracy if you're not very experienced in shooting, especially if it's a range gun. Take into consideration if it's DA/SA, DAO, SAO, or whatnot. If it's a defense gun, you should still take it into consideration, but not as much as the next two.
2. Buy for reliability/durability. There's nothing more frustrating than a gun that can't cycle your shots, and there's nothing more life-threatening than a gun that doesn't go "bang" when your life is on the line.
3. Buy for ergonomics/looks. Comfort is essential, but I didn't need to tell you that. A friend once told me, there's no point in buying a gun that you can shoot well with but think looks like ass - you'll only be frustrated and preoccupied with your purchase, and other things, like concentration, won't be able to follow.
Since you can't go CCW, you may as well go for the size that fits you best instead of one you can conceal more easily, and any big-name pistol should give you everything you need.
Just as a personal note: I originally liked the Beretta a lot, but I found the trigger pull to be absolutely horrendous... some people love it, others hate it, but that's probably the only reason I left you with that first tip
Good luck and safe shooting!
